The network for 'cellular response to external stimulus' in your query organism is displayed on the left, if relationships are supported by the integrated data. Moving any of the genes in that network will simultaneously update the homologs in the networks displayed to the right (if they exist). Additionally, hovering over any nodes will highlight the identified functionally similar homologs in the other networks. Last, the bar above the networks allows you to remove/add additional organisms. Simily drag and drop the organism names in the desired order.
